1. Why Does the Coating Spray Hose Matter in Pharmaceutical Manufacturing?

A typical tablet coating system consists of:

Coating solution tank → Pump → Transfer hose → Spray gun → Tablet surface

Although the hose is a small component in the overall system, it directly contacts the coating material and influences:

• Fluid purity
• Spray consistency
• Cleaning efficiency
• Equipment reliability
• Production stability

A general-purpose industrial hose may introduce risks such as:

• Chemical swelling or degradation
• Extractable contamination
• Material migration
• Surface adsorption
• Difficult cleaning procedures

For pharmaceutical applications, the hose should provide:

✔ High cleanliness
✔ Chemical resistance
✔ Smooth internal surface
✔ Low extractables
✔ Good flexibility
✔ Long service life

2. Common Coating Solutions and Hose Material Selection

Tablet coating formulations vary significantly depending on the pharmaceutical process.

2.1 Water-Based Coating Solutions

Common materials include:

• Hydroxypropyl methylcellulose (HPMC)
• Polyvinyl alcohol (PVA)
• Polymer dispersions
• Pigment suspensions

2.2 Solvent-Based Coating Solutions

Some film coating processes use organic solvent systems, including:

• Ethanol
• Isopropanol (IPA)
• Acetone
• Ethyl acetate
• Mixed organic solvents

These applications require higher chemical resistance.

Common issues with unsuitable hoses:

• Swelling
• Hardening
• Permeation
• Reduced service life

3. Key Factors When Selecting a Pharmaceutical Coating Hose

3.1 Chemical Compatibility

The first selection factor is always the coating formulation.

Before choosing a hose, confirm:

• Chemical composition
• Solvent concentration
• Temperature
• Exposure time

For aggressive chemical environments:

Recommended materials:

• PFA
• PTFE
• FEP

For flexible pharmaceutical liquid transfer:

Recommended materials:

• Platinum-cured silicone

3.2 Cleanliness and Extractables

Pharmaceutical production requires minimizing contamination sources.

Important hose characteristics:
